The DSC framework supports component oriented distributed communication architecture such as TINA (Telecommunications Information Network Architecture). Within the component development environment, components can be developed and evaluated. Software components are self-contained packages of code that can be dynamically linked into a program. Operational interfaces cater for the external functionality of the component. The DSC can support both dynamic and static operational interfaces. Also, there can exist multiple instances of the same operational interface. Furthermore, components can be grouped together to form compound components. Through a common control and configuration interface the components can be configured with regard to events, properties, operational interfaces life cycle, and composition. We apply this framework to a TINA based service and network architecture called MESH (Multimedia Services an the Electronic Super Highway). An example is provided; a shared white board service is created using the DSC framework. The shared white board service can be used in multimedia conferencing applications.","PeriodicalId":217490,"journal":{"name":"Proceedings Second International Enterprise Distributed Object Computing (Cat.

Information systems supporting concurrent engineering must facilitate the exchange and unambiguous interpretation of product data from various design and manufacturing stages, the collaboration of geographically dispersed experts in a complex design process, and the use of diverse computing platforms and tools. We describe our experiences in a joint project with the Department of Mechanical Engineering, building an integrated information system for concurrent engineering applications. The system is based on a single, integrated object-oriented data model and schema, the so-called product and production model, which covers all phases of the product life cycle. The model is implemented in a distributed and heterogeneous fashion using a CORBA-based object bus. On top of this bus, support for structured and ad-hoc collaboration is built around a uniform and flexible presentation layer We motivate concurrent engineering and argue why we believe that it mandates a single, integrated schema. We then describe the overall architecture of the system and address various implementation issues, in particular object persistence, model evolution, presentation services and support for collaborative work.","PeriodicalId":217490,"journal":{"name":"Proceedings Second International Enterprise Distributed Object Computing (Cat.

Such systems are increasingly deployed in open networks, such as the Internet, where resource allocation and load varies highly. To meet QoS requirements in such an environment, systems need to be able to dynamically (re)configure and adapt to changing QoS conditions. This paper describes a model for a QoS negotiation mechanism. The model allows clients and servers in distributed object systems to negotiate for QoS agreements involving multiple QoS categories, such as performance, reliability, security, etc. The model includes both a protocol that enables agents to negotiate and a technique for calculating the worth of alternatives. The protocol handles negotiations involving multiple offers and counter offers. It evaluates an offer based on the absolute requirements for QoS levels and their relative worth to the negotiating systems. The protocol and the worth calculations are part of a QoS negotiation model that involves simultaneous negotiation over multiple QoS categories. We describe how negotiating applications communicate and evaluate offers. In addition, we describe the functions the negotiation mechanism requires from its environment. The protocol has been formally specified and simulated. We are currently investigating implementation approaches and prototypes for the full as well as simplified versions of the described model.","PeriodicalId":217490,"journal":{"name":"Proceedings Second International Enterprise Distributed Object Computing (Cat.

With commercial availability of Smalltalk and C++, and the evolution of OT analysis and design methodologies together with their support in the form of CASE tools, OT has been incorporated into software development processes with greater benefits experienced as a function of its more pragmatic application. The business environment in which OT has matured has evolved significantly since the 1970's. Businesses typically operated monolithically and self-contained with their own purchasing, accounting, and human resource groups (among others), and centralized corporate IS groups that served as architects, implementers, and maintainers of customized mission critical software systems. IS groups effectively comprised closed software development organizations that totally controlled software systems core to corporate business. OT was used in this type of closed organization principally to implement custom business applications. Given the changes in the evolving business environment it is beneficial to re-examine Object Technology as it may apply to the extended enterprise.","PeriodicalId":217490,"journal":{"name":"Proceedings Second International Enterprise Distributed Object Computing (Cat.
